Incorporating Pulse-Tube two-stage machine technology, these 4K helium cryostats are ideal for scientific laboratory applications. They are used in a wide variety of applications: magneto-optical properties, RAMAN-e spectroscopy, THz or mm-wave imaging, characterization of cryo-electronic components, characterization of ultra-high stability oscillators, characterization of superconducting devices, etc.
The ambient temperature flange of the cold head is mechanically disconnected from the cryostat by an adjustable vacuum-tight bellows. The cryogenic cooler is thermally connected via flexible thermal links developed by Absolut System. This mechanical decoupling ensures high thermal stability and low vibration levels.
In addition, to guarantee an ultra-quiet thermal and mechanical environment for highly sensitive experiments, such as SQUID-based applications, we can develop cryostats with on-board helium liquefaction. They can also operate in recondensation mode if required.
Thanks to its teams of cryogenic engineers, Absolut System designs and manufactures complete equipment to specific specifications. Assembly is carried out in our workshops, and tests are carried out by our technicians. Our teams are on hand to support you during on-site integration and commissioning.

Absolut System designs specific Dewars and liquid nitrogen optical cryostats for laboratory and space equipment research.
The liquid nitrogen cryostat enables macromolecular diffraction experiments to be carried out by cooling all forms of samples to 77 K. It is very common for cryostats of large biological macromolecules to show considerable variations in the quality of their diffraction. The large number of samples tested means that diffraction quality can be improved prior to full data collection.
The Storage Dewar is capable of robot operation and can be integrated into a fully automatic macromolecular X-ray beamline in synchrotron facilities. A subset of 3 pucks (30 samples) is positioned in front of two loading/unloading ports with an automatic turntable. An observation port is available for viewing and reading the data matrix camera on each sample loaded into the dewar.
Designed from G11 fiberglass shells and polyurethane foam insulation, they are optimized to limit liquid nitrogen consumption (< 1.2 l/h at full operation). Static insulation also eliminates the need for vacuum and maintenance equipment, for a more affordable price and reduced size.
The liquid level inside the dewar is measured continuously and can be monitored as an option. Liquid nitrogen is distributed via a 2-meter-long flexible cryogenic line, an in-line phase separator and a cryogenic solenoid valve. Pressurized LN2 (600 mbar) flows from a self-pressurized LN2 reservoir through an insulated vacuum transfer line to the gold-coated temperature-controlled sample holder and through a heat exchanger for reheating to the cryostat exhaust.
